Application filed August 15,1901. Serial No. 72,100. (No model.)

To (bZZ whom it nutg concern.-

Be it known that I, JOHN E. ROBINSON, a citizen of the UnitedStates,residing at Philadelphia, in the county of Philadelphia and Stateof Pennsylvania, have invented certain new and useful Improvements inSoaprapping Machines, of which the following is a specification.

My invention relates to a machine for inclosing bars of soap and otherlike solids in envelops of paper or other suitable material and inpasting and drying the folded ends of each package prior to its deliveryfrom the machine.

Myinvention consists in certain novel features in the construction andarrangement of the parts of machine hereinafter fully described, whichare shown in the accompanying pages of illustrations, in which- Figure 1represents a plan view of the machine, with the chute for delivering thesoap to the machine shown in dotted lines. Fig. 2 illustratesa sideelevation of the machine, with the soap-carrier in position to receive abar of soap from the chute. Fig. 3 shows a rear end view of the machine.Fig. 4 illustrates a detached perspective view of the rolls for feedingthe paper to the folders, the folders, and knife for severing the paper.Fig. 5 shows a detached perspective view of the soap-carrier about todeliver a bar of soap to the folders, with the upper-end folders down ina position to release the fingers which hold and guide the soap. Fig. 6represents a detached perspective view of the side-folders in action,showing the paper partly covering a bar of soap. Fig. 7 illustrates adetached perspective view of the top-folders acting upon the paper, theupper-end folders at this point of the operation being withdrawn. Fig. 8shows a detached perspective View of the folding mechanism, in which theside and top folders remain in position to hold the soap and wrapperwhile the upper-end folders are brought down to form the first-endfolds. Fig. 9 represents a detached perspective View of the second-endfolders in position, with the upper-end folders still in position tohold the soap. Fig. 10 shows a detached perspective view of thepaste-rollers about to deliver a layer of paste to the last folds. Fig.11 illustrates a detached perspective View of the last end folders inposition. Fig 12 represents a detached perspective view of thedryingframe and steam-boxes for drying the pasted ends, with the plungerand plunger-rod delivering a package to be dried. Fig. 13 represents aside elevation of the cam and its connections for operating thefeed-rolls and plunger. Fig. 14 shows a side elevation of the cam andits connecting-levers for operating the soap-carrier. Fig. 15illustrates a side elevation of one of the cams and theirconnecting-levers for operating the side-folders and paper-knife. Fig.16 shows a side elevation of one of the cams and its connectingleversfor operating the folder plates, which engages the fingers of thesoap-carrier prior to acting in the capacity of upper-end folders. Fig.17 represents a side elevation of the cams and connecting-levers foroperating the top-folders. Fig. 18 illustrates a side elevation of thecams and connections for operating the second-end folders. Fig. 19 showsa side elevation of one of the cams and its connecting-levers foroperating the lastend or bottom folders, and Fig. 20 shows a sideelevation of one of the cams and its connecting-levers for operating thepaste-roller.

Referring to the reference-letters of the drawings, A represents theframe of the machine; B, the paper-feed mechanism; C, the carrier; D,the folding mechanism; E, the pasting mechanism; F, the drying-frame,and G the plunger mechanism for discharging the package into thedrying-frame.

The paper-feed mechanism comprises the upper feed-roll B and lowerfeed-roll 13*, which are geared together by spur-wheels B and 13,mounted upon shafts B and B", which support the feed-rolls. The shafts Band B are respectivelyjournaled in boxes Bland B, which are guidedinstandards 13 and are capable of being adjusted by means of set-screws Bpassing through the cross-pieces B and 5 hearing against the upper boxesB Upon the shaft B is mounted a clutch B comprising a toothed collar Bsliding upon a feather Z1 and backed by a spiral spring S. Upon a sleeve13, which encircles the end of shaft B is a correspondingly-toothedcollar B having inclined teeth engaging similar teeth on the collar BThe sleeve B is provided with a pinion B operated upon by a racklever B,which is guided in an oscillating shoe B fulcrumed upon the shaft 13Motion is imparted to the rack-lever B by a connecting-lever B fulcrumedupon a shaft B and having a short arm B provided with a weight B. Thelever B is provided with a roller B which is acted upon by a cam Bdriven by the cam-shaft H. The cam-shaft H, which carries all of thecams for operating the movable parts of the machine,is driven from themain driving-shaftH by spur-wheels H and H the former being mounted uponthe shaft H, which has fast and loose drivingpulleys H and H and thelatter upon the cam-shaft H. Motion is conveyed from the pinion B to theplunger mechanism G by means of a spur-wheel G, meshing with the saidpinion and engaging a spur-wheel G mounted upon a shaft G jonrnaled inbearings g in brackets G and motion is transmitted from the shaft G tothe rack G? and plunger G by a pinion G The plunger-rack, which is inthe form of a long toothed rod square in cross-section, is guided inbearings G and G the former being supported by a cross-bar G extendingfrom one to the other of the brackets G and the latterbein g supportedby the knife-plate l.

The paper supplied to the feed-rolls B and B is in the form of rolls Band B supported upon shafts B and B mounted in bearings B and B on theframe B which are arranged on either side of the machine and bolted tothe frame A. The upper roll of paper B which constitutes the outerwrapper of the package, may be of any quality and may be printed in anydesired manner as it passes to the feed-rolls. The lower roll B whichforms the inner covering of the package, I desire to be of a kind thatwill not adhere to the inner body and which when it is desired to coversoap and other like bodies will prevent the softer constituents of themass from passing through and damaging the outer covering, and for thisreason I desire to use for the inner covering a paper which is eitherglazed or coated with paraffin.

The bars of soap, caramel, or other like solids which it is desired tocover are conveyed to the carrier mechanism by an inclined chute J, themouth of which is directly in alinementwith the carrier 0. The bottom ofthe chute J is provided with a latch J, hinged at a point J and havingan upwardly-projecting ledge J which serves to hold the bars of soapagainst sliding when the carrier has moved away from the mouth of thechute. The latch J is operated in one direction by a spring S guidedupon a rod J having an adjusting-nut J and in the opposite direction bythe action of the bottom of the carrier 0, pressing upon theprojectingledge J The carrier 0 is mounted upon an arm 0 operated tomove forward and backward by a shaft 0 which is jonrnaled in bearings 0bolted to the table A of the machine. The ends of the carrier 0 areprovided with fingers O, which are acted upon by springs S to hold thebar of soap within the carrier. These fingers are moved against theaction of said springs when the carrier is in a receiving position byarms G which are fastened to the brackets G The shaft 0 which operatesthe carrier 0, is provided with a pinion O operated by a rack-bar C",guided in a shoe C fulcrumed upon the shaft 0 The rack-bar C isfulcrumed to a rocking lever 0 jonrnaled on a shaft B having a short armC provided with a weight 0 Upon the lever C is pinned a roller 0 whichis operated by a cam 0 secured to the cam-shaft H.

The folding mechanism D comprises in part a bed-plate D, to which arehinged a series of plates or folding members D D D and D which arearranged in pairs, the two former members operating together to form theside folds and the two latter members operating in unison to form thelast folds, which complete the package. The folding-plate D is providedwith a knife-blade I to sever the paper fed in by the rolls B and B andis arranged upon arms (1 (1 some distance away from the top of the plateto allow sufficient space for another of the folding members to passbetween it and the top of the member D in forming the top fold. Theplates D and D are provided, respectively, with short arms D and Dpinned to connecting-rods D and D which in turn are fulcrumed to theends of levers-D and D supported upon rods d and (1 The levers D and Dare provided with rollers 01 and d, which engage cams D and D mountedupon the cam-shaft H. The top folders D and D constitute plates alike incharacter and mode of operation, except that the latter is caused tomove by virtue of the cam arrangement slightly in advance of the former.These plates are hinged, respectively, upon rods (1 and d", which aresecurely fastened against turning to duplicate fulcrumed levers D and Dfulcrumed on rods R and R, provided, respectively, with rollers d and dand operated by cams D and D driven by the cam-shaft H. The levers D andD are operated against the action of the cams by springs S ,extendingfrom one to the other of each of the sets of levers. Fastened to therods d and d are stops d and 61 upon which the plates D and D are causedto rest by means of spiral springs s and s", the object of thisparticular varrangement of the plates just described being to cause thefront edge of the plates to act with yielding pressure against the paperas it is being folded, so as to cause it to closely surround thecontents of the package, and as the plates advance by virtue of theirconnection with levers which travel through the arc of circle the platesat the limit of their movement are so adjusted as to rest at all pointsupon the package and hold it firmly in place during the operation of thenext set of folding members. The first set of end-folders or upper-endfolders I) constitute bifurcated plates provided at the top withoutwardlyprojecting connecting-pieces d, which prior to their operationas end-folders act, as shown in Fig. 5, to release the contents of thecarrier O. This is accomplished by cutting the operating-cams in such amanner that the plates D will move down upon the paper before thecarrier reaches the point of delivery, so that the ends of the fingerswill be brought in contact with connecting-pieces (Z and release thefingers G. The plates D are connected to arms D fastened to verticalrods D guided in bearings 61 and (Z fastened to the frame of themachine. The rods D are provided at the bottom with arms D havingrollers (Z which engage cams D on the cam-shaft H. Upon the rods D arecollars (Z and between these and the bearing (Z is a spring 5. Thesecond-end folders or middle-folders constitute plates D and D fastenedto fulcrumed levers D and D supported on rods R and R and provided withrollers (Z and (Z operated by cams D and D on the camshaft H. The leversD and D are connected together and caused to operate against the actionof the cams D and D by springs S The last-end folders orbottom-folders,which constitute the plates D and D are provided withshort arms D connected to rods D, which are hinged to links D pivoted tocam-levers I). The cam-levers D are provided with rollers d, which en-'gage cams D- on the cam-shaft H.

The pasting mechanism E, which consists in part of paste boXes ortroughs E, provided with cylinders E are arranged on opposite sides ofthe folding mechanism adjacent to the bottom folders. The cylinders Eare mounted upon shafts E having pulleys E which are driven from themain driving-shaft H by pulley E The belts E are guided in groovedrollers E supported by bearings E fastened to the under side of thetable of the machine. The paste-boxes E are provided with adjustableplates e, which remove the surplus paste as the cylinder revolves,leaving but a thin film upon the surface thereof. Mounted in bearings E?above each of the paste-cylinders is a shaft E provided with arms E, inwhich are journaled rollers E which are caused to swing from thepastecylinder into the path of the bottom folders by means of crank-armsE As the bottom folders move upward the last folds of the paper arebrought in contact with the pasterollers, which also rise under theaction of the folders and deliver a thin film of paste to the paper asit is about to be closed against the end of the package. oted to aconnecting-rod E hinged to a link The arm E is piv-' E which isconnected to a cam-lever E The cam-lever is fulcrumed to the frame ofthe machine and provided with a roller e, which is acted upon by a cam Eon the camshaft H.

The drying-frame F comprises a table F, secured to the rear end of themachine by brackets F and provided at its sides with hollow chambers orboxes F which are heated by steam conveyed through inlet-pipes F andafter circulating through the chambers is discharged through pipes FAfter the packages have been completed by the folding and pastingmechanism they are pushed by the plunger G rearward into thedrying-frame, where they are slowly passed forward between the boxes Fby each incoming package and the folded ends secured before they reachthe end of the drying-frame.
